I typed out a big post and it got eaten, so I'll make this second attempt brief.
American Seaboard; Uruguay; Nigeria. Three valuable colonies that should each have a reasonably sturdy station flagship (ignore the Caribbean, I have plans sorted out there). What to do, though?
1) A big monitor with 1x3 350mm, 15-20 knots
2) A panzerschiffe with 2x3 280mm or 300mm, 26-27 knots
3) Two pre-dreads with modern fire control, so 4x2 280mm and ~18-19 knots
Overseas drydock requirements are the same-ish. Costs for new monitor or panzerschiffe hulls are about the same-ish. Resources saved by using pre-dreads will pay for ~1.5 new battleships or armored cruisers.
What would you build?
In order of preference 2), 3), 1). Pocket battleships can be useful in a wide variety of roles while monitors are more single-purpose and I would take 3 pocket battleships over 1.5 armored cruisers.
To me, the main difference between 2 and 3 is do you expect to fight anyone that has sufficient large armored cruisers to make the 26-27knts insufficient to run away from likely opposition? If you dont have the speed advantage, the slower predreads would be preferable to me as you get two instead of one plus a large armored cruiser of your own.

I'd nope the Monitor right out. 1 x 3 is too few guns for decent fire control, not to mention all eggs in one basket. If anyone has an AC with 10in guns or something, they could reasonably beat the monitor in a gunnery duel despite the effectiveness of the 35cm guns. Monitors have their use, but fighting on the high seas at this point isn't one of them, even in coast defense you need a minimum 4 main guns for FC purposes.
The Panzerschiffe would make for more flexible ships than the pre-dreads, and possibly the ability to upgrade their powerplants for more speed in 10 years or so. Keep in mind what their speed is and what you anticipate the speed of any AC of 8in or larger to have for the near future, say 5 years or so. In the coast defense role they can reasonably outrun a lot of BBs, and 6 x 28cm guns should be sufficient for fire control to engage cruisers at medium and long range.
The Pre-Dreads functioning as coast defense ships would be the toughest, and probably able to see off any cruiser, even if they can't run them down. But keep in mind that any stray BB can walk them down and smash them in a gunnery duel. Pre-dreads as coast defense ships historically had a longer run than as line of battle ships, the Scandinavians were using them into WW2 with some usefulness.

I think my challenge at this point is that I don't have a clear and specific rival to fixate on. I've had the spat with Iberia, so there's that. I share colonial borders with Rome, Parthia, Iberia, the Incans, the Confed of 5 Nations, and the Mayans, so theoretically could experience friction with any of them. There are a lot of competing design philosophies there to take into account.
Caribbean-wise, I reckon I'll be moving a squadron of modern capital ships there so they can help cover off America, Uruguay, and otherwise take care of my Caribbean interests, like that big ditch I've started digging.

I had started out on the panzerschiffe road by looking at analogues to the Swedish
Sverige - but concluded that, cost-wise, it wasn't terribly hard to scale up to six guns, and then speed came up...
I do usually look at possible mid-life speed increases as I go, but my current panzerschiffes don't have a lot of seakeeping to spare thus far.
Byzantium prefers combat groups
2 PD rebuilt - 22kts + 2 or 3 AC -24kts - 27kts.
If you can rebuild a PD (12-15 years old max), that's fine. If not,
Panzerschiff 24kts and better armor with AC.
How about a 22-24Kts PD built in 1914?

I've not yet been sold on rebuilding PDs. Modernizing their FC and maybe their light battery is fine, but a replacement of machinery, change of bunkerage, and updating of the main battery presents a cost that approaches replacement value (particularly once scrap value is added in).
I'm also skeptical of building new PDs, which is why my Sverige clone evolved into a six-shooter with heavier protection and longer legs. The monitors are potential exceptions only because they're mounting the biggest gun I have in service.
If I was going to do a monitor for coast defense purposes and not supporting ground troops, I'd have 4 guns.
What would it cost you to do 2 twins or 2 triples with the 35cm guns on more of a monitor setup? That would fend off anything other than a full up battleship, and would likely cause a battlecruiser to decide to go elsewhere to play as the chances of getting a serious hit would be too high to justify the risk of pounding the monitor into scrap.
Otherwise, I'd say go with the panzerschiffe out of the options presented. More flexible, just don't try to use it as a primary cruiser, but rather a colonial cruiser with a particularly heavy battery.
You can always do a mix, say PDs for Africa and South America, and a couple Pocket Battleships for the American colonies. Then down the road you replace the PBs with proper capital ships and send them down to replace the old PDs.
I hadn't looked at a 2x2 35 cm ship, but that's worth checking into. I'd have to develop the twin turret so that puts me off to a 1915 date, no biggy.
Two triples is more capable but then I'd probably just scale up to my ongoing 3x3 BB program anyway.
Certainly a mix of stuff is an option. The Szczyt is operational, so I can park it somewhere even nobody likes big monitors.
Ultimately I'm using the Sultan Ali class BCs for this in the Pacific. 280mm x 8 BCs. But then I need ships that can steam for 10,000nm and you don't.

You could swap VTE to turbines, but you have to add Electric Drives as your final drives due to the vast difference between the shaft runs of the two.
Ah, okay.
Interesting question Rocky.
The Mallet designs the Parthians submitted to the Incas are modifications of designs I've played with to answer this question.
Heavy offensive armanent - While fire control suffers with fewer barrels, and survivability is less with fewer turrets, I presume the foe will be faster and can pick the range, so make it hard to figure out a good one to pick.
Enough armor to force the foe to close to kill you...at which point you should be able to kill them.
Preferably enough speed to stay away from predreads and early dreads.
Good torpedo craft defenses.
Being able to hide in shallower inshore waters is likely a plus.
So the most out of a little package is good for affordability.
For colonies far from home fleets, if they have to dispatch major units for months to hunt down a PD/Pocket BB, that's a win, weakening the home fleet you might be trying to fight.
Armored Cruisers :
I really like the idea of armored cruisers for some reason, but they've already inflated to huge sizes and become battlecruisers already. Plus the length needed for speed & size makes supplying repair docks pricey. I'm really been looking at what are essentially 9" heavy cruisers- like the Norse, as a midsized answer for the role of defeating smaller cruisers and being independent flagships, while leaving Battlecruiser/Fast battleship types to compliment the line of battle.
PDs
I had long considered upgrading my PDs later, which is one reason I went for big powerful ones instead of small cheap ones.
I was hoping they would maintain some fighting capability. I think the Smurgh and Rakash classes do, but the older Turtle does not.
Jefgte's work on rebuilding some of his led me to take a hard look at what rebuilding would mean.
Guns are vexing issue, as the old turret barbette is limiting, but I have researched new ones that can fit in the old barbettes.
Even so, I've found the total cost of new guns, engines, etc....is a bit less than a new vessel in $, and much less in BP.
As colonies start generating $ , BP will become the limiter on construction.
So the 'Bang for the Buck' is there.
On VTE/Turbines : Yes, moving to turbo-electric is doable. But since 1/4 of the weight has to be set aside for engines,
simply replacing the VTE with new VTE is turning out the better option in some cases - in particular where Max speed is limited by seakeeping.
Certainly the smaller with your guns

There is definitely a niche for colonial cruisers/pocket battleships. Ships capable of taking on a pre-dread or old armored cruiser, while not being overly expensive.
I am seriously considering the Owari class small BC as the Australian flagship, 8x10", 27kts, on 11,000 tons.

Break time !
Took me a little bit to find it as it wasn't under battlecruisers. Then a bit to see how you fit that much on that hull.
Then I poked about and got sucked into a wild goose chase, thinking the Owari class has the same critical flaw as I noticed with your Maya class.
But if an 84% belt doesn't get a you a warning, and 0.84*0.65 = 0.546% of length, then
the fact your armor deck only covers 55% of the length doesn't matter.
Maya, with 107% belt, would be at 0.6995 vitals, but only 35% covered by the armored deck.
Not sure but the Maya also looks like the TDS doesn't actually cover from the bottom to the waterline, guessing you added 0.25m draft but didn't recalc the armor.
Ahh I should get back to work, getting emails and a
